No, you should not bake a cake in plastic. Baking requires subjecting the cake to high temperatures, and most plastics are not designed to withstand such heat. Baking a cake in plastic can lead to the plastic melting, releasing harmful chemicals into the cake, and potentially causing a fire in the oven.
For baking, it is essential to use oven-safe materials such as metal, glass, or ceramic bakeware. These materials can handle the heat of the oven without any safety concerns. Common options include metal cake pans, glass baking dishes, or silicone molds designed specifically for baking.
Always follow the instructions and recommendations provided by the cake recipe and the manufacturer of the bakeware to ensure a safe and delicious baking experience.
